Some kind of woven wood shade that fits inside the window? What are you countertops going to be? Or... something to bring in the blue/green in the backsplash tile and the wall color in the adjacent rooms. Maybe a textured nubby fabric (made into a roman type shade) with light colors and threads of the blue/green.

My granite is giallo ornamental... I was also thinking along the line of roman shades, but didn't know if they would be the wrong style?

Your kitchen elements are beautiful. What a wonderful
space.
Here are some ideas, maybe they can help you.

I did a similar backsplash and noticed my current shades had too many vertical lines--it just looked really busy. I did a very simple linen roman shade with a border out of contrasting fabric. Don't know how to post pics or I would. I really like it.
